I've only just become aware of this float - http://www.aquatica....omponents.html. Presently, I'm using ULCS double buoyancy arms which go some way to offset the negative buoyancy of my camera rig. Stix or foam floatation is out of the question as these products are neither use nor ornament at technical diving depths. I'd be grateful for comment and opinion about these (or similar floats?) from fellow WP'ers and also their depth rating (Jean?)
